5.3 Voltage Measurement
1. Turn Selector Dial to Voltage Mode (V posion)
2. Select Voltage Mode then press
buon to connue
3. Connect probes to circuit to be tested red=posive(+), black=negave(-)
4. Display will then show correct voltage
While measuring voltage, the Status Indicator will also illuminate to give a quick indicaon of correct voltage for 5V, 12V or 24V power sources
For example when measuring voltages from a vehicle ECU
Good
Voltage OK
Marginal
Check Voltage
Low/High
Voltage outside limits
